First suggestion for this hat, I found 3 recent sales (+ sales from comments):

"Quickselling" for 1 bud, got a Blizz Liq Lid instead (1.15*0.9 ~ 1 bud) :

He bought the unu on this trade for 15 keys (outlier) [url]http://www.tf2outpost.com/trade/16934582[/url]

Edit (thanks to the comment) : The last guy got the coupe in offers :

For this unusual :

As the Bombing Run is worth 17 keys, the offer should be superior than 17/0.9 in unusuals ~ 19 keys ~ 1 bud (so fits to the price suggestion of the Coupe)
